A recent news story got me thinking about old technology we might be about to lose in the name of progress, and the cultural impact that might have.

The EU has made a move to ban all tungsten light globes based on their low power efficiency. Tungsten bulbs are the ones that would come to mind when you think “light globe” - not Fluorescent or LED.

There has been objection in particular in the theatre and film production industries - tungsten globes have been used in these industries for over 100 years and to a certain extent inform the “look” we are used to.
Tungsten bulbs have a certain “colour temperature”, simple distribution of light frequencies, and a predictable nature.
The loss of tungsten bulbs won’t kill theatre or film - but it will never quite be the same again.

So my question is, what consumable technology are you aware of of which we have finite stock?
